If you are a real handyman, you might have done some metal works, not to mention joining and installation. Yet, if you have some experience and you are ready to pick up the gauntlet of repairing metal gates or welding a pedal to a bicycle, a MIG welder is what you need! A few welding methods are known such as MMA, TIG, MIG, and MAG. We will look through MIG welders in our review. A MIG welder uses a streaming inert gas that acts as a shield and expels air contaminants from a weld zone. If no gas is used, the seam is porous and infirm. We will review household MIG welders plugged to a power outlet. Such welders can fuse stainless steel sheets and weld cracks and holes on cars, etc. We have examined 5 best MIG welders to help you buy an appropriate model for your welding needs. Also, we advise paying attention to sandblasts and that will help you get the surface prepared before welding, as well as angle grinders for cutting metalware.
How to pick a welder tips: MIG wire inch button: A great feature. This will save you wasting your shielding gas when feeding wire through at the start of a new reel. Gas purge button: Another nice option. Save yourself some MIG wire, when you’re setting your gas flow. Burn back facility: Not all machines have this externally, buy it’s good to be able to trim the burn back to the wire according to the application & operator. Selecting the correct amperage machine: Generally, you should work on 35-40 amps per 1 mm diameter of material to be welded.
One of the “cardinal sins” that almost every shop commits is over-welding. This means that if the drawing calls for a 1/4″ fillet weld, most shops will put down a 5/16″ weld. The reasons? Either they don’t have a fillet gauge and are not exactly sure of the size of the weld they are producing or they put in some extra to “cover” themselves and make sure there is enough weld metal in place. But, over-welding leads to tremendous consumable waste. Let’s look again at our example. For a 1/4″ fillet weld, the typical operator will use .129 lbs. per foot of weld metal. The 5/16″ weld requires .201 lbs. per foot of weld metal – a 56 percent increase in weld volume compared to what is really needed. Plus, you must take into account the additional labor necessary to put down a larger weld. Not only is the company paying for extra, wasted consumable material, a weld with more weld metal is more likely to have warpage and distortion because of the added heat input. It is recommended that every operator be given a fillet gauge to accurately produce the weld specified – and nothing more. In addition, changes in wire diameter may be used to eliminate over-welding.
Several tips about welding equipment, MIG and TIG welders, plasma cutters. When appearance counts, TIG welding creates a high quality, clean weld that is far less likely to distort the metal by using a nonconsumable tungsten electrode. There is no need to worry about splatter because it only uses the necessary amount of filler metal needed in the welding puddle, making for the highest quality weld in every respect. However, TIG is fairly specialized and requires a good deal of training in order to master it—so make sure any TIG welder purchase is paired with a plan to take welding classes. Instead of the point and shoot simplicity of MIG welding, TIG requires the use of a foot pedal to regulate the welding process. A filler rod that is separate from the torch that must be fed in gradually. Many professional welders prefer TIG because it can weld a wide variety of metals and because of the versatility of argon gas used during TIG welding. There is no slag to block the view of the weld puddle. Argon gas can weld any metal at any thickness with TIG welding, and therefore there is no need to change the gas depending on the project.

USA market choice: Through our extended research of these particular welders, we found dozens of videos and articles and reviews to guide the viewer through the process of buying, setting up, and using these machines. We hope this buying guide will help you in choosing the welder that most suits your needs. After further explanations of the welding process and what to look for when buying, there will be a list of ten well-known metal inert gas welders that will each be reviewed briefly.
The Hobart Handler 230 is unmatched in its field. It’s a powerful welder that can comfortably weld 1/2 inch steel in single phase with fantastic arc quality. Other features include a 60% duty cycle at 175A, 12 different voltage settings, and infinite wire speed control. It’s a huge unit, but there’s wheels to help move it around, and a build in cylinder rack to store your gas cylinder. Most hobbyists won’t need a welder this powerful, but if you want a reliable MIG welder with a bit of extra power, this is our top pick. You can read the full review here.
